Which type of resource does the specified AWS policy define access for?

The specified AWS policy likely defines access for an EC2 instance because policies in AWS are used to control permissions for various AWS services and resources. When designing an IAM policy for an EC2 instance, the policy might include actions such as starting, stopping, or modifying instances, which are specific to EC2 services.

AWS IAM policies use a JSON structure that clearly indicates which actions are allowed or denied on particular resources, and the context of the question suggests that the focus is on the compute resources provided by AWS. Many policies specifically grant permissions related to the deployment and management of EC2 instances, which are pivotal in cloud computing environments.

In contrast, other resource types mentioned—like S3 buckets, EBS volumes, and Lambda functions—would have their own distinct IAM policies that detail access control for those specific services, often including different actions and resources tailored to each service’s functionality. Each service operates under different paradigms and permissions, making EC2 a natural focus based on the context of the question presented.
